Is your company/department looking to upgrade their database hardware? If so, Oracle has made it easy for any organization to join the big league and opt for an Exadata solution for about $250,000. Oracle is willing to ship a Quarter Rack with certain hardware turned off to your organization allowing the benefit of an appliance that is designed to supercharge your database applications. This configuration of Exadata is an ideal action for bringing the technological advancements as well as extreme performance for smaller workloads.
Alternatively, if your Development or QA servers are not on Exadata, or are hosing your production servers, an Eighth rack is a good option to isolate that environment where the Developer and QA can work assuming an exact replica of production.
Review the comparison between the two configurations here:
